Filter Options
Activated carbon filters are designed to eliminate smells and volatile organic compounds (VOCs) from the atmosphere, making the air fresher and cleaner.
They work by using porous carbon material to catch and neutralize pollutants and aromas. Activated carbon filters are ideal for removing gases and smells, especially in areas with heavy traffic or smokers.
You can find air purifiers with filters packed with activated carbon, often in pelleted form. The higher the amount of carbon, the better the air purifier will be at removing gases and smells from the air.
